Hi @Stefan Schippers, I'm trying to get the total power consumption of the design that's done in Xschem. Cadence Spectre has a nifty tool that can save total power signals to output and I'm wondering if there is a way to replicate that functionality within the simulation tools available to Xschem.

From @Stefan Schippers the easiest way is to save the supply currents and supply voltages, then sum the products of

current * voltage

. ngspice has also the ability to calculate the power consumption of an entire subcircuit:

* power dissipation of a subcircuit device

. probe p ( XU1 )

@StefanCK Thank you for linking the message.
